How a government system can get to using centrally issued IDs is exactly what we are trying to do in British Columbia with VON (https://vonx.io). We are building out the supply side of Verifiable Credentials of government IDs (public ones, initially) to create a demand from Organizations (run by Individuals) to be Holders and Provers of those Verifiable Credentials. Any jurisdiction can make use of the VON tools/techniques to participate in building that demand.
Data breaches that have made someone knowing a tax-id irrelevant as to whether they are the subject of that ID has made the standalone use of those IDs pretty much useless - online or off. Requiring the presentation (proof) of a claim of that ID from a Verifiable Credential issued by an authorative source is of value, and is exactly what will motivate governments to move to this model. We believe this model will be a far cheaper and scalable vs. traditional IP/IAM systems.
